2.在ThemeRoller官方页面下下载主题，获取jQuery UI主题文件。
使用
解压下载好的压缩包，在项目的根目录下建立相应的文件夹，将文件放入文件夹中，目录如图示：
如图所示
添加如下代码
<link rel="stylesheet" href="jQueryUI/jquery-ui.min.css">
<link rel="stylesheet" type="text/css" media="screen" href="jqGrid/css/ui.jqgrid.css" />
<script src="jqGrid/js/jquery-1.11.0.min.js" type="text/javascript"></script>
<script src="jqGrid/js/i18n/grid.locale-en.js" type="text/javascript"></script>
<script src="jqGrid/js/jquery.jqGrid.min.js" type="text/javascript"></script>
实例
在数据库中建表，准备数据
建表
CREATE TABLE invheader (
invid int(11) NOT NULL AUTO_INCREMENT,
invdate date NOT NULL,
client_id int(11) NOT NULL,
amount decimal(10,2) NOT NULL DEFAULT '0.00',
tax decimal(10,2) NOT NULL DEFAULT '0.00',
total decimal(10,2) NOT NULL DEFAULT '0.00',
note char(100) DEFAULT NULL,
PRIMARY KEY (invid)
);
测试数据dataupload,xls文件转为csv导入数据库。

PHP文件
<?php
//include the information needed for the connection to MySQL data base server.
// we store here username, database and password
// to the url parameter are added 4 parameters as described in colModel
// we should get these parameters to construct the needed query
// Since we specify in the options of the grid that we will use a GET method
// we should use the appropriate command to obtain the parameters.
// In our case this is $_GET. If we specify that we want to use post
// we should use $_POST. Maybe the better way is to use $_REQUEST, which
// contain both the GET and POST variables. For more information refer to php documentation.
// Get the requested page. By default grid sets this to 1.
$page = $_GET['page'];
// get how many rows we want to have into the grid - rowNum parameter in the grid
$limit = $_GET['rows'];
// get index row - i.e. user click to sort. At first time sortname parameter -
// after that the index from colModel
$sidx = $_GET['sidx'];
// sorting order - at first time sortorder
$sord = $_GET['sord'];
// if we not pass at first time index use the first column for the index or what you want
if(!$sidx) $sidx =1;
// connect to the MySQL database server
$db = mysql_connect('127.0.0.1', 'root', '') or die("Connection Error: " . mysql_error());
// select the database
mysql_select_db('test') or die("Error connecting to db.");
// calculate the number of rows for the query. We need this for paging the result
$result = mysql_query("SELECT COUNT(*) AS count FROM invheader");
$row = mysql_fetch_array($result,MYSQL_ASSOC);
$count = $row['count'];
// calculate the total pages for the query
if( $count > 0 && $limit > 0) {
$total_pages = ceil($count/$limit);
} else {
$total_pages = 0;
}
// if for some reasons the requested page is greater than the total
// set the requested page to total page
if ($page > $total_pages) $page=$total_pages;
// calculate the starting position of the rows
$start = $limit*$page - $limit;
// if for some reasons start position is negative set it to 0
// typical case is that the user type 0 for the requested page
if($start <0) $start = 0;
// the actual query for the grid data
$SQL = "SELECT invid, invdate, amount, tax,total, note FROM invheader ORDER BY $sidx $sord LIMIT $start , $limit";
$result = mysql_query( $SQL ) or die("Couldn't execute query.".mysql_error());
// we should set the appropriate header information. Do not forget this.
header("Content-type: text/xml; charset=utf-8");
$s = "<?xml version='1.0' encoding='utf-8'?>";
$s .= "<rows>";
$s .= "<page>".$page."</page>";
$s .= "<total>".$total_pages."</total>";
$s .= "<records>".$count."</records>";
// be sure to put text data in CDATA
while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$s .= "<row id='". $row['invid']."'>";
$s .= "<cell>". $row['invid']."</cell>";
$s .= "<cell>". $row['invdate']."</cell>";
$s .= "<cell>". $row['amount']."</cell>";
$s .= "<cell>". $row['tax']."</cell>";
$s .= "<cell>". $row['total']."</cell>";
$s .= "<cell><![CDATA[". $row['note']."]]></cell>";
$s .= "</row>";
}
$s .= "</rows>";
echo $s;
?>
效果如图

友情提示：关闭php的display errors选项，否则会因为数据库的问题报错。
